UNetbootin allows you to create bootable Live USB drives for Ubuntu, Fedora, and other Linux distributions without burning a CD. It runs on both Windows and Linux. You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list. This method of getting a live install to a USB drive is the simplest available using Unetbootin. Note that we will format the USB drive and erase its contents.

Note: you can now save changes made to the system across reboots (persistence).
